Research Posters – Pathology Research Posters – Cytotoxicity and Biocompatability.

The article presents abstracts of various research papers related to pathology. One of the papers investigates immunohistochemically the presence of T helper/inducer and T cytotoxic/supressor lymphocytes in apical granulomas and cysts. Periapical lesions which were to be treated surgically were used in this study. Twelve histologically identified granulomas and nine apical cysts were immunohistochemically stained employing the immunoperoxidase technique. Positive cells were counted under the light microscopy and analysed statistically. Another paper studies the influence of electronically controlled periapical instrumentation on the healing of chronic periapical lesions in the teeth of dogs.
